Title: System and method for data interpolation in a multislice x-ray computed tomography system

Abstract: The present invention comprises a system and method for producing images of an object utilizing an x-ray computed tomography (CT) system. Detector elements within the CT system provide raw projection data representing the attenuated x-rays. A data corrector modifies the raw projection data to account for errors to produce corrected projection data. A high order interpolator operates on the corrected projection data to provide estimated projection data at the exact spatial position of the desired image. The high order interpolator utilizes a cubic spline function to determine the estimated projection data. The estimated projection data are used by an image reconstructor to perform high speed image reconstruction.
